Tonight I had to stop for petrol on the way home. A number of the unleaded pumps were closed off, and the rest were occupied. I pulled in behind the person who appeared to me to be closest to finishing up and pulling out of the station. He was washing his windscreen at the time.

He proceeded to meticulously squeegee not only his windscreen and rear windscreen, but also each of his side windows, his wing mirrors and his headlights. Carefully, and in great detail.

I wouldn't have complained, except for the fact that it was raining at the time.
